Cleaning, deep cleaning and SteraMist decontamination compared

How basic cleaning, deep cleaning and SteraMist decontamination compare, and where each fits when dealing with mould, bacteria and other pathogens.

Published 7 February 2024

Cleaning and deep cleaning can appear to “do the job,” but on their own they typically only offer a basic level of protection from health hazards such as mould spores, bacteria, viruses and other pathogens.

SteraMist decontamination uses ionised hydrogen peroxide technology. It’s used across a range of industries including food production, pharmaceuticals, healthcare, education and transport.

Basic cleaning

  • Cleaning down with a cloth, using a domestic-grade cleaner.
  • Removes an estimated 99.9% of visible dirt and residues from surfaces. Has little effect on airborne contaminants.
  • Typically leaves behind an estimated 40-60% of contaminants.

Deep cleaning

  • Cleaning with a more advanced commercial cleaning product.
  • Typically applied with fogging sprayers and left to dwell on surfaces.
  • Many products contain aggressive chemicals such as ammonia, chlorine and esters, which can cause respiratory and skin irritation.
  • Typically leaves behind an estimated up to 10% of contaminants.

SteraMist decontamination

  • Uses Cold Plasma Arc technology and a 7.8% hydrogen peroxide BIT solution.
  • The fine mist disperses like a gas, reaching surfaces including inside ductwork.
  • Cleanliness is validated with a laboratory report.

Contaminants referred to above include micro-organisms such as mould, bacteria, algae, viruses and other pathogens, and chemical contaminants such as mycotoxins, volatile organic compounds (VOCs), microbial VOCs (MVOCs), formaldehyde and dioxins.
